IMPROVEMENT IN WATCHMENS DETECTERS.

Specification forming part of Letters Patent No. 213,135, dated March11, 1879; application filed October 4, 1877.

To all whom it may concern:

Be it known that I, GUsrAV H. ROTH, of the city of Boston, county ofSuffolk, and State of Massachusetts, have invented certain new anduseful Improvements in atchmens Detectors; and I declare that thefollowing is a full, clear, and exact description of the same, referencebeinghad to the accompanying drawings, and the letters and figures ofreference marked thereon, which make a part of this specification.

The object of my invention is to connect with the ordinary mechanism ofa clock a registering device for printing upon a strip of paperappropriate letters or figures to indicate the time of day or night thatthe device may have been operated upon by the watchman, thus furnishinga printed record of the exact time the watchman is attending to theduties required of him by his employer.

In the accompanying drawings, Figure 1, Sheet 1, is a general plan of myimproved device as it would appear upon the removal of the dial of theclock, its position being in front of the ordinary running-gear of theclock, which it is not deemed necessary to represent, except such partsas are immediately connected with this device.

(t represents the ordinary post or arbor, carrying the hour-hand of theclock, made sufficiently long to admitthe placing thereon of theprinting-drum 1). (Shown also in Figs. 1 and 2, Sheet 2.) Around theperiphery of this drum a metallic band is placed, having thereon, atappropriate intervals, raised letters or figures to correspond with thehour as represented by the hands on the face of the dial, care havingbeen taken to adjust the hands so as to correspond with the figures onthe drum.

The hour-figures are made suiliciently long to nearly cross the bands,while within the space between the figures representing the hours,one-quarter, one-halt, three-quarters, &c., may be placed smallerfigures, to indicate the minutes. An enlarged developed section of thisband is shown in Fig. 3, Sheet 2.

On the face of the drum 1) is placed the spur gear 0, and on each sideof the drum 1) are placed two guide-rollers, c and f, provided withsuitable flanges, for the purpose of holding in an appropriate mannerthe strip of paper to be printed on. Sectional views of these rollersare shown in Figs. 1 and 2, Sheet 2.

The roller f is held in position in appropriate bearings in the hingedlever g, hinged, that it may the better adjust itsolfto its appropriateposition, while the spring 7b is so arranged and adjusted as to give thenecessary pressure. The adjustment of the roller fis fully shown in Fig.1, Sheet 1, and Fig. 2, Sheet 2.

The roller 0 is adjusted, in an appropriate manner, upon the spring i,as shown in Fig. 1. The roller 0 carries upon its face the smallspurgear d, which meshes into the large gear 0. The gear (I is madesmaller than the guiderolier c, and is rotated by the large gear 0, forthe purpose of creating a slight friction and strain upon the strip ofpaper which runs between the drum 1) and the roller 0, in order to keepthe paper tight upon the dial-band around the periphery of the drum 1).

In the upper part of Fig. 1, Sheet 1, is the casej, a sectional view ofwhich is shown in Fig. 4, Sheet 2. It is adjusted to its place by anappropriate slide attached to the case of the clock. This case is forthe purpose of holding the roll of paper to be printed on.

In the sectional view, Fig. 4, Sheet 2, the spool k is shown, upon whichthe paper is rolled, and within which a spiral frictionspring is placed,in a similar manner and for a similar purpose as the one within theribbon-spool I, Fig. 1, Sheet 1.

The spools in both cases are made hollow, and a small strip of suitablemetal is rolled up and adjusted within the same for a friction-spring,for the purpose of retarding the motion of the spool and creating aslight strain upon the ribbon of the spool I, Fig. 1, Sheet 1, and spool70, Fig. 4, Sheet 2.

The strip of paper on, Fig. 1, Sheet 1, upon the spool within the casej, is drawn over the guide-roller and between the same and the dial-drumI), thence around the under side of the same, and up between the drum Z)and the guide-roller c, from which it is carried through appropriateguides to and through the side of the clock-case, as shown at n, thatthe printed record may be read upon the outside without opening the caseof the clock.

Sheet 2) are placed, for the purpose of cutting off the paper atpleasure.

The spring 19 is for the purpose of holding open the movable jaw of theshears, to enable the paper an to pass freely through between the jaws.

The wire 1*, adjusted to the movable jaw of the shears, is for thepurpose of enabling a person to cut the paper when the clock is placedabove reach.

Upon the spool 1, Fig. 1, Sheet 1, is placed a ribbon, s, which isprepared with such coloring-matter as is generallyused in thepreparation of printing ribbons; This ribbon is 'passedthroughappropriate guides directly beneath the paper m, as itvpasses under theprinting or dial drum 1) and between said drum and the roller t, fromthence it passes between the guide and tension rollers 10 a. The guideand tension rollers 1mare adjusted in appropriate' bearings in thesupport or bracket 'v,

the bearings for one of the rollersbeing so made as to admit of a slightlateral movement.

Upon each side of the bearings of the rollers a u, and attached to thearbors of the rollers, is the serpentine spring 20, which holds therollers firmly together, and at the same time permits them toaccommodate themselves to any slight inequalities in the ribbon 8. Thesetension-rollers are best shown in Figs. 5, 6, and 7, Sheet 2, which showa plan, and longitudinal, and vertical section of the same.

Around the vertical center of the tensionroll u, (shown in Fig. 7, Sheet2,) isplaced a toothed friction-wheel, a", the teeth of which extendslightly beyond the periphery of the roll, for the purpose ofholding-securely the ribbon 8. At one end of the same roll is placedanother toothed or ratchet wheel, 2. (Best shown in Fig. 6, Sheet 2.)Connected with this wheel is the pawl a which prevents the wheel fromturning backward.

Above the tension-roll a, and connected with the ratchet-wheel a, is theself-acting click 0', attached to the angular lever b. This lever isbest shown in Fig. 9, Sheet 2, which also shows the hour-wheel of theclock, d, upon the radial arms of which are placed one or moretripping-pins, e e, which, acting upon 7 the lever b, actuate theself-acting click a,

and thus turning the tension-roll u a gentle strain is given to theribbon s.

The sprin g f Fig. 1, Sheet 1, presses against the angular lever b, andforces it back into position whenever it is actuated by the pins 0 andthe arms of the hour-wheel. (Shown in Fig. 9, Sheet 2.)

The spring h (best shownin Fig. 9) is for the purpose of pressing theself-acting click a. back into position after being actuated by thelever 11. 4 I

Fig. 12, Sheet 2, shows what may be termed the printing-levers t" and k.(Shown also in Fig. 1, Sheet 1.) The lever klishingedupon the post l,Fig. 1, Sheet 1, upon which it is allowed a slight oscillating motion.Upon the other end of this lever, transversely arranged in anappropriate slide-bearin g, m, is the friction-roll t. On one side ofthe slide-bearing of the roll is the irregular spring-lever 'i, theother end of which is firmly attached to the lever is. Upon the oppositeside of the slidebearing m" is thespring it- In Fig. 1, Sheet 1,directly beneath the lever I k, is the irregular lever 0, another viewof which is shown in Fig. 10, Sheet 2. This lever carries at the upperend the spring 19.

The post 1", Fig. 1, Sheet 1, is so placed that when the lever 0 is inits normal position it presses the spring p down from beneath the leverk. The lever 0 is hinged upon the post 8. Beneath the lower arm of thislever is the eccentric-lever t, hinged upon an appropriate post, andextending downward through the bottom of the case of the clock.

At the extreme end of the horizontal arm of the irregular lever 0 is thespring 12, one end of which being attached to the lever and the other tosome appropriate part of the clock, draws the lever firmlydown upon theeccentrics of the lever t.

It will be seen that, by drawing the lower end of the lever t either totheright or left, the same motion is imparted to the irregular lever 0-that is to say, the horizontal arm of the lever 0 will be forced upward,giving'an upward and longitudinal motion to the upper arm of the lever 0in aleft-hand direction, and as it passes the post 1' the spring isrelieved, and, press- 1 spring-lever i, pressing against the angle ofthe same and moving longitudinally, imparts an inward motion to thelever i, which forces the roll it across the face of the raised lettersor figures on the band around the periphery of the printing-drum b, alsopressing the ribbon s and paper in, firmly against the face of theraised letters or figures on the band around the periphery of thedrulnb, and. thus in a well-known manner prints upon the paper theletters or figures on the dial-band that happen to be next the wheel atthe time.

Having thus described my invention, what I claim a-s-new, and desire tosecure by Letters. Patent, is

1. In a watchmans detecter connected with the ordinary running-gear of aclock, the combination, with the hour post or arbor of such clock, ofthe wheel I), carrying on its periphery a band having raised letters orfigures thereon, indicating the hours by large figures, and the quartersby figures of less size, (best shown in the developed section, Sheet 2,Fig. 5,) made and adjusted substantially as described.
